The ExtrudeSrf command creates a solid by tracing the path of the surface edges in a straight line.

**Steps**

1. Select a surface.
2. Specify a[ ](https://docs.mcneel.com/rhino/8/help/en-us/popup_actions/distance_pick_2pts.htm)distance.

#### Command-line options

-SetBasePoint

* Specify a location that serves as the first point when picking two points that set the extrusion distance.

-Direction

* Two points establish the direction angle
* Direction steps

  1.Pick a base point.

  2.Pick a second point that establishes the direction angle

-BothSides

* Draws the object on both sides of the start point, creating the object twice as long as you indicate.

-Solid

* If the profile curve is closed and planar, both ends of the extruded object are filled with planar surfaces and joined to make a closed polysurface.

-DeleteInput

* Yes: Deletes the original geometry.
* No: Retains the original geometry.

-ToBoundary

* Extrudes the object to a boundary surface
